To all whom it may concern..-

Be it known that I, HENRY G. VOIGHT, a citizen of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

My invention relates to locks, and particu larly to one in which I have provided both a knob-controlled latch and a key-controlled bolt, the same being arranged in the novel and compact manner hereinafter fully explained.

The object of my invention is to simplify the construction of a lock including a bolt as well as a latch mechanism and to so arrange the parts that they may be assembled and tested preparatory to being fitted to a door and then quickly applied.

In the drawings, Figure 1 is a plan view of a lock of my improved construction. Fig. 2 is a vertical section thereon on the plane of the line 2 2, Fig. 1. Fig. 3 is a horizontal section of a portion of the mechanism, showing the latch-bolt, part of a slide, and the support therefor. Fig. 4 is a plan view of the inside of one of the frame-plates of the latch and lock mechanism. Fig. 5 is a similar view of the inside of the other plate.

1 designates what I shall term a frameplate for one side of the door-for example, the inside.

2 is a frame-plate for the outside of the door. The plates 1 and 2 are provided with rose members 3 4, respectively, which constitute long bearings for the knobs 5 6, respectively, which are held in place in any approved manner.

7 is a latch-slide, the main body of which is in the form of a comparatively thin though stifl' sheet of metal, which slides on the inner side of the plate 2 and may be guided by the bearings 8 9. The slide 7 is provided at its rear extremities with the shoulders 71 71, which are engaged by the roll-back 10, which is mounted on the inner end of the knobshank 61 of the knob 6. The latch-slide is bent at its forward end so as to extend toward the latch 11, which in the form shown is pivoted at 11 to the frame-plate 2. The frame-plate 2 is extended at its end adjacent to the latch 11 so as to form the end plate 12 to cover the edge of the door. The end of the slide 7 adjacent to the rear of the latchbolt may be divided and may carry a pin 72, which stands in the slot 11*, formed in the back of the latch-bolt 11, so that as the latchbolt operates the pin will slide to and fro in said slot.

13 is a spring carried by frame-plate 2 at the rear of the latch-bolt 11 and pressing against said latch-bolt to force it outwardly under normal conditions.

14 is a spring plate or clip, the ends of which may stand in notches underneath the bearings 8 9. This spring plate or clip 14 stands over the inner end of the shank 61, roll-back 10, and slide 7, and when the parts are assembled said clip lies substantially flush with the inner surface of said plate 2.

15 15 are bosses having screw-threaded openings to receive the screws 15 15, which may pass through the inner plate 1 and engage with the outer plate, so as to securely clamp both the plates against opposite sides of the door.

16 is an ordinary knob-spindle, the ends of which may enter squared openings in the knob-shanks 51 61, whereby said knobs are connected together, so that the rotation of either knob will cause the roll-back 10 to rock, and thereby cause the slide 7 to retract, withdrawing the latch-bolt 11. Immediately below the slide 7 and mounted upon the plate 2 is a second slide 17, the end of which may form a bolt 18. This slide may have two slots arranged in its line of movement. Projecting into one of said slots is a screwstump 19, carried by the frame-plate 2, and a stationary stop or abutment 20, carried by the frameplate 2. These parts 19 and 20 serve to assist in guiding the slide 17 and insuring its straight-line action. Any desired number of tumblers may be provided as desired; but in the form shown I have provided only one tumbler 21, the same being pivoted at 21 on the slide 17, so as to move therewith. The slide 17 has a recess in its lower edge, as indicated by dotted lines in Fig. 4, into which the bit of a key may project to move said slide when the tumbler or tumblers 21 respond to the action of the key and cause the bill 22 of the tumbler to stand above the stop 20. It will be seen that this bill 22 of the tumbler will stand on one side or the other of the stop 20, and thus hold the bolt 18 either in or out, as desired.

23 is a spring, one end of which may be projected into a slot in the tumbler 21 near its pivotal bearing, the other end of which may be bent around the pivoted end of the tumbler and engaged underneath the stud 24 on the latch-slide 17. The action of the spring 23 is such that the tumbler will norto mally move so as to cause its bill 22 to engage in front of or behind the stop 20.

25 is a guard-plate secured to the inner side of the plate 2 and having a keyholeopen-' ing therein in line with the keyhole-openings 26 27 on the plates 1 2, respectively. This guard-plate 25 may be secured to the plate 2 in any convenient mannerfor example, by means of screws 28 28. A suitable coveringplate 29 (see Fig. 2) may be secured above the tumbler 21 to hold it in place and to in turn hold the slide 17 close to the inner wall of the frame-plate 2. This covering-plate 29 may be secured by means of a screw 30 taking into the stump 19. Obviously this plate should not be attached so tightly as to prevent the free movement of the tumbler 21 and slide 17. This plate 29 is preferably located in approximately the plane of the inside of the frame-plate 2; but the guardplate 25 may project slightly beyond this inner plane. The plate 1 may have a sliding connection with the end plate 12, for example, by means of extensions 31 31, which project into spaces between posts 32 32, carried v 35 by plate 2 and extending approximately parallel with the inner side of the face or end plate 12 and spaced apart slightly therefrom. These posts 32 32 are in turn guided between shoulders 31 31 on the extensions 31 31. By this means an interlocking and guiding arrangement is provided, which prevents the plates 1 2 from being twisted apart under ordinary strains and secures the correct alinement of all parts and facilitates the easy operation of the latch mechanism by turning either knob. 33 33 are back-stops to the rear of the slide 7 and on the inside of the frame-plate 2 to limit the inward excursion of the slide 7. The slide 17 may be limited in its rearward excursion by the inwardly-turned flange at the edge of the plate 2, or, if desired, stops similar to those indicated at 33 may be provided. In assembling the look the parts may be assembled and tested prior to being applied to a door. In this manner it may be 38061:

tained whether the slides and various moving; parts work properly. In applying the lock to a door the stile or edge thereof is sawed into slightly, holes are bored for the screws 15 15 and the spindle 16, and the surface of the door adjacent to the guard-plate 25 and adjacent to the ofiset portion of the slides 7 17 5 may be cut away sufiiciently to permit said parts to lie properly in place. The plates may be then moved apart or separated and applied to the door on opposite sides thereof and adjacent to said cut-away portion. The spindle 16 is inserted during the act of ap- 7o plying the plates. By setting up on the screws 15 the plates and the associated parts are clamped together securely and firmly against the outer and inner side of the door in such a manner as to hold the faceplate 12 securely in the notch at the edge of the door. Obviously if a screwless knob were provided at either end of the lock the spindle 16 could be inserted after the lock is applied to the door. The screwless knob is too well known to require illustration. It is obvious that by this mechanism the labor and expense of forming a mortise in the door are entirely avoided. No sufficient portion of the door is cut away to weaken the same. The parts may be applied or removed from a door readily and quickly. The invention has particular utility in connection with car-doors. In practice when cars are renovated or repainted the hardware is removed. As a re- 0 sult it frequently happens that lock parts of the type now used are lost or misplaced. By my invention this is impossible, since all of the parts of the lock may be secured together or assembled to await the time when it shall 5 be desired to again apply the lock to a door. In the form in which the spindle is introduced just prior to fastening the knob onto the plate it is unnecessary to take the lock apart save to remove the knob and spindle in order to remove or apply the lock. What I claim is i 1. In a lock mechanism, the combination of two separate frame-plates adapted to be applied to the opposite'sides of a door, ad 10 5 justable to and from each other, an end plate secured to one of said frame-plates having an opening for the passage of a locking-bolt, a locking-bolt having a shank guided by one of said frame-plates, a spring-pressed tumbler, no coacting with said lockingbolt, a guard-plate carried by said latter frame-plate, said frame- 7 plate and guard-plate having keyhole-openings and means for adjustably securing said frame-plates together; 1 I 5 2. In a lock mechanism, the combination of two separate frame-plates adapted to be secured to the opposite sides of a door, an end plate carried by one of said frame-plates and adapted to extend across the edge of a door, coacting means carried by said frame-plates adjacent to said end plate, permitting the lateral adjustment of said frame-plates but preserving their alinement, a knob carried by each frame-plate, a locking-bolt carried by 12 5 said second frame-plate having its head adapted to project through said end plate, the tumbler for said bolt, each of said frameplat'es having a keyhole-opening for access to said tumbler and said bolt. 13o

3. In a latch mechanism, the combination of two separate frame-plates adapted to be secured to the opposite sides of a door, an end plate carried by one side plate and adapted to cross the edge of a door, coacting means carried by said frame-plates adjacent to said end plate for preserving alinement of said plates, but permitting their adjustment to doors of difierent thicknesses, a latch-bolt adapted to protrude through said end plate, a slide carried by the side plate which carries said end plate, a knob carried by each side plate, means of connection between said nobs and said slide including a spindle extending from one knob across the space between the frame-plates to said slide-carrying plate.

4. In a latch mechanism, the combination of two separate frame-plates adapted to the opposite sides of a door and adjustable to doors of different thicknesses, an end plate carried by one frame-plate and adapted to extend across the edge of a door, coacting means carried by said frame-plates for preserving their alinement relative to one another but permitting their lateral adjustment, a knob carried by each frame-plate, a locking-bolt carried by one frame-plate having its head adapted to project through said end plate and adapted to be engaged by a key, a guard carried by the same frame-plate which carries the bolt, each of said frameplates and said guard-plate having a keyholeopening for access to said bolt.

5. In a latch mechanism, the combination of two separate frame-plates adapted to the opposite sides of a door and adjustable to doors of different thicknesses, an end plate carried by one frame-plate and adapted to extend across the edge of a door, coacting means carried by said frame-plates for preserving their relative alinement but permitting their lateral adjustment, a latch-bolt adapted to protrude through the end plate, a knob carried by each frame-plate, means carried by the same frame-plate which carries the end plate for operatively connecting its knob and said bolt, and means of connection between the opposite knob and the latch-bolt including a spindle extending across the space between the frame-plates.
